is an organic fluid known as semen that usually contains spermatozoa. It is secreted by the gonads (sexual glands) and other sexual organs of male or hermaphroditic animals, including slugs, for fertilization of female ova. The process of discharge is called ejaculation.

One of many slang words for semen. The male reproductive fluid, semen (or jizz) consists of a soap-like substance (secreted by the prostate and seminal vesicles), sperm, fructose (non-sweet sugar), and water. Its major purpose is to fertilize the ova (or "eggs") in most mammals and select other jawed vertebrates, and it goes by MANY names. It is secreted in the process scientifically known as ejaculation, during the male orgasm.
